a quick hummer h1 question...

i just got a 2002 H1 but the guy had lost the books to it, so i haven't had this question answered. can you air up the tires (or check air pressure) in any way OTHER than the CTIS? my CTIS works fine, i was just curious since i didn't see a nozzle to air it up.
thx,
lance

Yes U can, the only thing you have to do, is to take out your rim´s cover, and there is a nozzle where you can check the air pressure.
